SAFETY-PIN CATCH.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed April 2, 1914. Serial No. 828,975.

To all whom it may concern:

Be it known that I, THOMAS S. BENNETT, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Safety-Pin Catches, of which the following is a specification.

This invention relates to safety-pin devices and applies, more particularly, to ornamental or jewelry pins such as scarf-pins, brooches, and beauty-pins which it is desirable to securely fasten in place to prevent accidental detachment and loss.

The object of my improvements is to produce a device of this character which will possess advantages in point of convenience, security and general etliciency.

The invention consists in a rotary sheath or guard adapted to engage the pin tongue when the same is introduced into the guard and is thereupon held until the guard is manipulated to release the tongue.

The invention relates, further, to details of construction, which will be hereinafter described with reference to the accompanying drawings, in which Figure 1 is a side elevation of a jewelrypin embodying my invention and illustrated with the tongue engaged. Fig. 2 is an underside plan view of the same. Fig. 3 is an end elevation thereof. Fig. 41 is a fragmentary longitudinal vertical section of Figs. 1 and 2. Fig. 5 is a view similar to Fig. 4: with the guard in disengaged position. Fig. 6 is an underside plan View of Fig. 5. Fig. 7 is a sectional view on line 7-7 of Figs. 1 and 2.

The reference numeral 10 designates the body of the pin which, in the illustrated embodiment, is provided with a pair of ears 11 near one of its ends and a pair of ears 12 near its other end.

13 represents the tongue connected by a pivotal pin it with the ears 11 and of a length to extend into the space intermediate the other ears 12. The guard or sheath for the tongue is formed of two side members 15 which are preferably of circular form and are connected at diametrically opposite sides with transversely arranged bars 16 and 17. Extending axially outward from each of said members are trunnion elements 18 which are journaled in apertures 19 provided in the ears 12. As illustrated, the ele ments 18 are of tubular form and are stamped or pressed outwardly from the respective members 15, said elements being secured against withdrawal from the ears by fianging the same over the latter asindicated at 20.

A protuberance 21 (Fig. ll is provided on the outer face of one of the members 15 and is located so as to contact with the rear edge 12 of the adjacent ear 12 when the guard is in the position in which it is represented in Fig. d, and afford a stop which will cooperate with the tongue 13 to yieldingly retain the guard against accidental rotation such as would withdraw the bar 16 from the tongue. The protuberance likewise contacts with the other edge 12 of the referred to ear when the guard occupies the position in which it is shown in Fig. 5 for the purpose of yieldingly holding the guard against rotation in the direction indicated by arrow as in Fig. 5. hen sufficient force is, however, exercised to turn the guard, the resiliency of the guard structure will allow the member provided with the protuberance to be deflected inwardly by the sloping outer surface of the latter acting wedge-like against the opposing ear.

To engage the tongue 13, it is pushed against the bar 17 as indicated by arrow (Fig. 5), thereby causing the guard to be rotated as shown by arrow as to swing the bar 16 below the tongue so that when the latter is brought thereagainst, it is arrested by the bar, as clearly shown in Fig. 4. To release the tongue, the operator pushes with his thumb nail against the bar-edge 16 to thrust the same from the tongue and in so doing rotates the guard into the position whereat it is shown in Fig. 5. When the tongue engages the bar 16, the plane underside of the bar seats upon the tongue and tends to maintain the guard against rotation and contributes with the aforesaid protuberance in securing the tongue-point so that the same is not liable to become disengaged through any accidental agency.

Having described my invention, what I claim, is

In a device of the class described, the combination with the body provided with depending apertured ears, of a rotary sheath comprising two side members, a palr of bars connecting said side members, and trunnions provided on the members to serve as axle elements in the apertured ears, said sheath being unprovided with an axle eX- Signed at Seattle, Viash, this 28th day Of tending between the side members to afford March 1914. 1 an open snace between said. bars whereby the a THOMAS S.
